The Homeland Security Investigations (HSI) Innovation Lab is developing an analytical platform called the Repository for Analytics in a Virtualized Environment (RAVEn). RAVEn facilitates large, complex analytical projects to support ICE’s mission to enforce and investigate violations of U.S. criminal, civil, and administrative laws. RAVEn also enables users to develop new tools to analyze trends and isolate criminal patterns as HSI mission needs arise. For more information, please read the DHS/ICE/PIA-055 - Privacy Impact Assessment 055 for the Repository for Analytics in a Virtualized Environment (RAVEn).
Within RAVEn, HSI has utilized artificial intelligence / machine learning to verify, validate, correct, and normalize the accuracy and quality of addresses, phone numbers, and names. The normalization services let agents analyze both well-defined addresses (such as those in CONUS and Europe) and less well-defined addresses (such as addresses using mile markers); standardize phone numbers to their identified country and to the E164 ITU standard; and streamline the process of correcting data entry errors and/or pointing out purposeful misidentification, connecting information about a person across HSI datasets, and cutting down the number of resource hours needed for investigations.
